Descripción

General description

Dimethyl sulfoxide (DMSO) is a polar solvent.[1] DMSO activated by electrophile (oxalyl chloride) has been used to oxidize various alcohols (primary, secondary, allylic, benzylic, hindered and bicyclic). Carbonyl compounds are formed as reaction products.[2] It has been proposed as an alternate solvent for methyl cellosolve for use in ninhydrin reaction, due to its high stability.[3]

Application

• Modification of gelatin by reaction with 1,6-diisocyanatohexane.: This study focuses on the modification of biopolymers using chemical agents, which could be relevant in contexts where DMSO is used as a reaction solvent ( Bertoldo et al., 2007).


• Characterization of O-acetyl-(4-O-methylglucurono)xylan isolated from birch and beech.: This research characterizes specific wood-derived xylans, potentially enhancing understanding of such biopolymers when dissolved in DMSO for analytical studies ( Teleman et al., 2002).

Caution

Fácilmente superenfriado, vuelve a fundir lentamente a temperatura ambiente. Producto solidificado que puede volver a licuarse por calentamiento a temperatura ambiente sin detrimento del producto.
